To aZZ who/m t may' concern.'

Be it know-n that l, JOSEPH F. ,llnNsL a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of (lhio, have invented'a new and useful Roll Cleaner or Polisher, of Which .the following is a specification.

Generally speakin this invention relates to rolling mills, and more particularly to tin plate mills. p

Those familiar with the operation i these mills understand the ditiieulties attending such operation, by reason,ot'foreignsub stances aceumulatingvand "adhering to the v surface of the roll, and the obgfeetof my ini vention is to'provide a simp e, e onomical :md elicient means .for'polishing the rolls through the medium of an abrasion surface secured to a carrier adapted to travel back and forth throughout the length of the roll onguide bars adyaeent, and running parallel with, the rolls.

ln the' accompan' represent a preferire vention,- `v

Figure l is a Jiront elevation of a set of rolls embodying my invention.

Figure 2 is an end vlam-partially in section, on line 2-2 Figure'.

Figure 3v is a transverse section through the carrier 17 on line 3-3 Figure l.

Figure fi is la partial enel view, the operating wheel 3, the motor M and the bracket 7, on one end of the housing, holding the guide bars 15. l

Figure 5 is a fragmentary perspective view, showing thelyoke 16 and the stem 19 of the carrier 17 and also the bracket 7 on the opposite end of the housing, carrying the guide bars l5.'

Figure 6 is a fragmentary view, showin the engagement of the guide bars Wit their adjustable holding brackets 'i'. See line 6 6 Figure 2. l t

Figure 7 is a View of bracket "lf-the oeuf trai boring 8 being shown in dotted line.

ll' and H represent the opposite ends of the mill housing, and R and R represent the upper and lower rolls, respectively.

Secured to the platform P is the standard S, and journaled in the upper end of the ing drawings, `which embodiment of my inf standard, as at l (Figure Il) is the shaft 2,

carrying at one end of the grooved Wheel 3, and at the opposite end the driving pulley 4.

Beneath the platform is the motor M, which is connected with the driving pulley e showing i by belt or cable 5. It is "obvious, of course, that this connection may be made by either cog or friction gear if desired.

Adjacent the upper roll R (Figure 2) is the obliquely disposed slot 6 cut through the housing H, and secured to the outside of housing H is the bracket 7. Bracket is provided with a ventral longitudinal bore y8, in which is 'slidably mounted the `stein or pistoni), carryimgY the cross-head or hold- 'ing bar l0 provided with the sockets 1l, as

shoivnin Figure l.

As shown in Figure 8 .in the bracket Ifdoes Inet extend clear through, but stops siiti'icientlyshort to leave the head l2 having a central threaded opening 13 in which is mounted the adjustingy srew 14. The braeket is so attached to Ithe housing as to bring the sockets-11 in the crosshead() to register with the slot 6. The opposite housingv il is provided with a similar slot and-bracket holding and 'adjusting device. i

15-15 represent what l have termed guide bars, running parallel With eaeh other, as Well as with the roll, passing through the slots 6, and rigidly secured in the sockets il of the cross-heads or holding hars l0. f

lt is clear that with this 'arrangement the guide bars can be adjusted in their relation to the roll. 4 y

Slidably' mounted upon the guide bars 15-15 (Figure 3), by means of the oppositelvudisposed yoke members 16, is the carrier l?, valso provided with a central 4longitudinal. boring 18, in which is slidably mounted the stem or piston 19 `carrying the 'abrasion block 20. Seated in the boring 18 is coil spring 21, the tension of `which may,

be regulated by the screw 22.

Attached to one end of the carrier 17, as at 23, is the cable 24, which passes through the housing H, around lthe grooved Wheel 3, back through housings H and H', around the idler carried by ,bracket 26, back through housing; H', and is attached to the opposite end of carrier 17,'as at 27.

To regulate the tension of this cable provide the idlers 28 and 28, respectively, carried on one end of spring controlled arms 29 and 29', respectively, the opposite ends of which arms are swingingly mounted in the vbrackets 30 and 30, respectively, secured to the housing H,

Wheel 3 is provided with a series of ein lili 2, the central boring I seA gli

lifotaili)- mounted, is at 32, is the reversinga liar or lever the lower end of which engages die reversing motor 3l, while the upper end extends upwardly nhove the holes 2li in 'ivi-wel 'll'ie operation oi my device is as follows:

llihen the motor 'is set in motion. the. wheel 8 will rotate in the proper direction to draw the carrier lT to one end oi the roll, :il which time a pin 34. inserted in one ol'V the openings fil. will engage the upper end oi" the reversing lever 3?, causinglr this lever to swing and thereby reverse the motor. which will then drive the wheel il in the opposite direction, drawing' the carrier li' to the opposite end of the roll, when the piu 3l will engage the opposite side of the reversinggv lever 33, causing it to again reverse the direction of the motor. and so on.

lt is obvious that it' the length of the roll is suilicieni to require the wheel to travel one complete revolution. only one pin `will he required, hut if the length of the roll is less than the circumference of the wheel, two pins will he required, es for instance 35 and 36.
